IMPROVEMENT IN VEHICLE-WHEEL HUBS.

Sprc'fication forming part of Letters Patent No. 162,477, dated April27, 1875; application filed January 14, 1875.

To all whom it may concern:

Be it known that I, JOHN H. HYMAN, of Tippecanoe City, Miami county,State of Ohio, have invented certain Improvements in Hubs, of which thefollowing is a specification The object of my invention is to strengthenthe hub of a wheel, in a cheap and efficient manner, in such a way thatthe bands require no fastenings, and will not drop off by the shrinkingof the wood. Myinvention consists in cutting circular grooves near tothe outer sides of the spoke-sockets in the hub, and also longitudinalgrooves between each spoke-socket, communicating with the twobefore-mentioned circular grooves. Into these grooves I run any suitablemolten metal, which, becoming cold, will contract, and thus verytenaciously encircle the hub, and prevent it from splitting. At the sametime the longitudinal as well as the circular bands will strengthen thespoke-sockets.

In order to more fully describe my invention I refer to the accompanyingdrawings, formin g a part of this specification, of which Figure I is aplan view of a hub embodying my invention. Fig. II is a sectional viewthrough line m 00, Fig. I. Fig. III is a sectional View through line 3y.

A is the hub, with spokesockets B. O O are the two circular grooves. D Dare the longitudinal grooves connecting the circular grooves O G. E isthe metal run into the grooves U and D.

I am well aware that patents are granted to (J. H. Guard and to O. W.Fillmore for strengthening hubs, but, as both these patentees use forgedbands and connections, and I cast the bands and connections directlyinto the'grooves in the hub, I disclaim all similarity or interferencewith said inventions and patents.

Having thus described my invention, I desire to claim The hub A, havinggrooves C and D filled with metal E, all combined substantially as andfor the purpose set forth.
